The influence of chin proportions on facial attractiveness

There isn’t a woman in the world that wouldn’t want to look more beautiful. Intuitively women use various make-up products to enhance a specific part of their face, to create better facial proportions and consequently increase attractiveness. Historically, facial beautifying has always been on a women’s agenda, and even the Egyptian women at the ruling of Queen Cleopatra, from the 1st Century BC, had at their disposal a whole rainbow of cosmetics.

Furthermore, physical attractiveness (the face including) is recognized as an important attribute in psychosocial well-being, and not only a temporary pleasing event upon being witnessed. The popularity of different apps doesn’t come as a surprise, especially amongst millennials, that are correcting facial proportions contributing to their self-esteem and popularity in sharing on social media.

Cross-cultural agreement on attractiveness suggests that there is something universal about attractive faces (and unattractive faces) that is recognized across individuals, cultures, and ethnicities.

This universal beauty, known for centuries, hugely depends on the facial features’ proportions. Our brains seem to be “prewired” to these mathematical proportions that illuminate attractiveness. Even the evolutionary biology study1 did not find a strong own-race bias in attractiveness judgments, but neither were the data consistent with familiarity, suggesting an important role for other factors determining universal attractiveness. The beauty is indeed universal.


In reality, patients coming for aesthetic procedures are not aware that aesthetic procedures are now more than ever assigned to provide overall facial attractiveness besides correcting signs of aging or merrily enhancing lips! We, aesthetic doctors, can confidently acknowledge that we truly deliver a “ beauty through science” thanks to the extensive research that has been done in this field.

Patients could easily identify some disproportions on their face, such as having a big nose or having thin lips, and ask for ways of possible correction of these disproportions. Sometimes they will identify global disproportions (having a too wide face) and seldomly, unless it is severe, a chin disproportion.

The chin, however, is a well-defined compartment that plays an important role in facial attractiveness.

Lacking chin projection, that is usually described as a “weak chin”, should always be pointed out, by the experienced and well-educated injector, to the patient during their global assessment. Understanding the cause of this issue and the necessity to correct it plays a crucial part in achieving global facial attractiveness.

Lack of chin volume in a younger patient comes from underlying bony abnormalities and overlying soft tissue deficiency that the patient is simply born with. It presents itself as a short chin characterized by a shortened lower lip to chin height relative to the lower face; or with a protruded bony chin characterized by a normal vertical height. In a mature patient, aging of the lower face can cause structural changes of the chin, volume loss, less toned and less firm chin, which all contribute to the changing of the ideal facial proportions.

Severe cases of chin disproportion, that unpleasantly affect one’s facial harmony, usually require a permanent solution using surgery. It is a straightforward decision for both the patient and the doctor.

However, there are still many patients that have disproportional chins, who do not require surgery, but that disproportion is still hugely affecting their facial appearance and attractiveness.

In such patients, an aesthetic procedure performing chin enhancement using dermal fillers can significantly add to their attractiveness.

But, are patients open to it?

The  study2 investigating the perception of facial attractiveness by assessing deferent chin deformities concluded that laypersons were as observant as doctors when asked to assess this issue. The purpose of this study was to find objective evidence (by including  laypeople) that chin deformities are a noticeable part of facial harmony, even if not severely expressed. And more importantly, if the chin was not protruding or recessing too severely, the layperson would label it as a feature adding to facial attractiveness.

This finding made clinicians, trained to assess even minor discrepancies in facial harmony, more open to discussing and suggesting chin augmentation to aesthetic patients.

The majority of these studies are done using profile pictures as that was the easiest way to demonstrate chin deformities and the contribution of the chin to the profile harmony after the treatments. Clinicians are likely to demonstrate to patients the effect of the well-balanced chin on facial attractiveness by using before and after profile photography. And although it wows them, they will only really be satisfied if they see a change in their portrait (their front view face), the view that they will be exposed to on a daily basis from looking into the mirror. That is why chin augmentation should not be performed alone but should rather be done after a full facial assessment of proportions and performed in conjunction with aesthetic procedures in the midface, temples, jawline, etc.


Although patients will rarely enter the practice asking for chin augmentation, this procedure is more frequently done than one thinks. It is a necessary part of almost every well-planned facial harmony restoration. In order to achieve high patient satisfaction for chin augmentation, we need to use suitable dermal fillers that support the uniqueness of a chin’s structure and yet also give natural and long-lasting results.

Because of the high expectation from patients of this not “so popular” procedure, I needed to make sure that I am using the product which has its performance backed up with

excellent scientific data, and that the product is primarily suggested for this area. The injectable hyaluronic acid (HA) dedicated for this area gives results suggesting long-lasting improvement in the chin projection and patients reported improved satisfaction as well as improved psychological wellbeing after the treatment.3, 4

Furthermore, this kind of a dermal filler provides a great lift capacity and because of its mouldable property it allows it to be sculptured into the desirable shape, which is much needed for the chin area.

According to GAIS  RR (Global Aesthetic Improvement Scale Responder Rate), 90% of physicians rated the chin and jaw area as being “improved” 3 months post injection, with improvement seen at 18 months, indicating effectiveness beyond this period.3

Improving attractiveness is as rewarding for the doctor as it is for the patient, but

performing the procedure with well researched tools gives a lot more confidence to the both of them.
